iBe it knoxyn that l, Josnrn ERNEST Trion'r'n, a subject or. the King of Great Britain;A residing atr the city' oi" Vancouver, in theflrovinceot" British. loluinbia7 Canada, ha'vei'nvented certain neu7 and useful lmarv'ei'nents' in l'Raaoiwtropping Devices, of which the followingA is a specification.

`My invention relatesto .improvements in devices for lstropping' raz-or' bladesAl with more particular reference t tvvo4 edged blades suchas'those'used in "tlie Well-lmown Gillette YVsafety razor, and the object of invention is to provide `a"si`inple Vand praetical device by meansot` whiclrsuch"blades maybe resharpener'l in'ahighly ertiicient and convenient manner. f y

Similar numerals of reference 'indicate similar parts throughout the several views.

The device consists of a`boX,' indicated generally by the numeral 1, of a size adapted to lie lcomfortably in the palm of the hand, having' the sides 2 yand 3, the ends 4t and 5, and the ton and bottom plates 6 and 7 the ends e and 5 being provided with slots 8 and 9r respectively of vsufficient length and depth to `permit oi the passage therethrough or the strop 10, While the bottom plate 7 is cut away at midleng'th of each longitudinal vedge to formgaps 11 and 12, as shown in Fig. 6, and adjacent each gap are erected vertical standards 13 and 14; between which extend and on'yvhich'are rotatably supported rollers 15 and 16.` Rotatably .mounted on the inside `of the end plates t and adjacent the slots .8 and `9 are small diameter rollers 17 and' 18 the peripheries of which project slightly below the upper edgelof the slots) While rotatably mounted transversely of the boXad'iacentthe underside vof the topl plate and towards each end respectively arelarger rollers 19 and V2O, and around these rollers and-the innermost 'ones 15 and 16 is passed the'ystro-ppinz'fi"beltA 10, the manner of its ar- Y y rangement.' beine; as shown in @that is, the upper po-rtiono'f the belt is laid around theupper rollers 19 and 2O and its freeends passed back parallel 'with the upper 'portion over the rollers y15 and '1 6 and under'the same to extendy under the rollers 17 "and '18 out through 'the respective end slots. 8 and9. One vendofV thefstrp is provided With an eyed' member 21" so' that it may be secured to alhook "Whi le 'its oppositer end is provided Withfa 22V in'which the finger maybe engaged to'hold the 'stlropv tight when loperating theidevice;` y

"intermediate its length and Vfreely supported at its opposite ends in suitable-bearings 24 and 25 formed on the sides 2 and 8 4respectively to which shaft are securedtlieside plates 26 and 27 of the blade carrier rocker; which sideplates "are" "provideidfwvith downwardly 'extending slotted armsiQSvand 2Q in the yslots of Which are en' gapd 'pinsill and'lv secured tojthe upper ends respectively of levers 32 and 33, these levers being fulcruned f l intermediate"` their length'oir-thestandards"13 and 14 by means of" a "shaftv 34' which vei'r'tend's 'freely throueh the standards and to lfthe 'eirds""`ofy which the levers ,aresec'ur'ed 35: and 36' indicate pins securednnto thelevers 323' and 33 adjacent their lower fendsfto'r 'a 'purpose hereinafter described.I I g f f The side plates oftheiblade carrier rocker are connected ltogetherby a transverse plate 37 Whichextends between them, as shown by the dotted lines 'inFigyfl andthe full linesin 5," and'thisfplat'e has a narrovv longitudinal slot 38 formed in it extending from end to end and communicating at each.

slot aforesaid7 andf'this opening-is'made in F ig. 2, the opposite end voit the bar be-V ing providedV with an upwardlyand baclrwardly'turned member 144 forming a hook.

Y on the top side ot the bar at its tree end. Secured into the bar 4l are three vertical pins 45 spaced to suit vthe spacing of the three holes found in the razor blade 46 and which^ pins, when the blade is placed on the bar 4l, project through the holes in the blade into corresponding holes 47 formed in an upper har 48 rigidly secured at one end to the cover plate 42, its opposite end extending closev to the point ot the hook 44 of the lower bar. This upper bar 48 is preferably wider than the lower bar and is provided on its top sidev with a guide slot 49 in which isslidably mounted orlongitudinal movement a locking bar 50 having an upstanding Vprojection 51 for operating it, and as the con struction is such that the outer end of the bar'50 lies opposite thejentrance of the hook 44 it will be seen *that the bar may be moved forward and backwardin the slot 49 to engage in the hoolr to detachably connect the upper and lower bars together or to be di-sengaged from the hoolr so that the bars may be parted fromieach other, or` in other words, the blade carrier may be opened or closed whenfthe locking bar is lmoved inthe required directions. 1

'The upper and lower bars 48 and V41` respectively are spaced apart at their outer ends Vby the thicknessot the end52 or"v the member 44 remote from its hooked end, as Y VVshown in Fig. 7, that is, when the bladev carrier is closed the outer ends of the blade 46 and of the upper bar rest on the end 52, and the space between the blade-and the lower bar and the width of the lower bar is such as will permit of the outer end oit the blade carrier, that is, the end remote from the coverV plate A42, being passed through the opening 40 and [entered into the T- shaped slot ot the side plate 26 and then pushed inwardly under slight hand pressure until the said end enters and isV seatedin the T-shaped slot ot the side plate 27, when the blade will be resting tightlyon the upper side of theftransverse plate 37 with the lower bar 41 frictionally engaging the'undersideof the plate. Y The Vclover plate 42 is then seated against the side ofthe boxclosing the opening 40 and in orderito prevent inadvertent outward movement of the blade carrier when the device is being operated the cover plate 42 is provided on its upper ring 22.

inet/,aia

edge with a short tongue 53 adapted to rock with the carrier behind a downwardly eX- tending lange 54 formed on the side of the box, the nge beingV provided with a notch 55 through which the tongue passes when seating the blade carrier in place. F or convenient withdrawal oi the carrier to remove oi' insert a blade the cover plate 42 isV provided with a linger ring 56 hingedly connected to it.

The operation ofthe rocker is eiected by means'of a bottom plate 58 mounted to lie on the bottom plate 7 ofthe box, which plate 58 is turnedupwardly at opposite ends te form sides 59 and 60 disposed to lie close to the sides 2 and 3er the box, the upper edges of which sides are' turned over inwardly to engage slidably beads 61 and 62 extending longitudinally on the top'plate ot the box, from which it will be yseen that the plate 58 is connected to the box and capable of longitudinal movement with relation thereto. At midlength the plate 58 is provided with upstanding jawniembers 63 and 64 projecting though the gaps ll and l2v of the bottom plate 7 normally engaging the pins 35 vand 36 of the leversY 32 and 33, while the side 59 is cut away to clear the cover plate 42.V` Y

The manner in which the device is used blade to be resharpenedfbeing placed in the Vblade carrier and the latter beinO inserted in the opening 40 and pushed inwardly to be seated von therocker the member 21 is hooked to a hook or a nail and the strop straightened out and held taut by the left hand, one linger or" which is inserte! i right hand the thumb of which bears on and grips the side 597er the plate 58 while the fingers bear* on and grip the side 60 and the box is then moved to and fro. At the `commencement of each movementof the for such independent movement before enr gaging the respective end edges of the slots to bel arrested thereby and move the box. `lldovement of the leversV in oneV direction rocks the blade rocker in the opposite direction, tilting it so that the opposite edges of the razor blade bear on the under side oi the upper portion of the strop and on the upper side ofthe underneath parallel portion, as shown in 4, andV thus, prior to Y the actual movements of the boX itself, the blade is rocked in opposite directions to bring the opposite edges alternately to bear The boX isv then gripped bythe on` the strop so that they are sharpened thereby as'theto` and fro movements ofthe lbox draw, the blade back and forth along the strop.

Fromfthe foregoing it willpbe seen that I havedevised a simple, practical and convenientstropping devicefor safety razor blades.
